Abstract: Cellulose is bleached by means of an organic peracid in the acid region and subsequently by means of peroxide in the alkaline region. As peracid there is employed an acid which is produced from the corresponding carboxylic acid by reaction with hydrogen peroxide in the presence of a mineral acid. The peroxide bleaching step which follows the peracid bleaching step is carried out after there is added the necessary amount of aqueous alkali solution for carrying out the peroxide bleaching step of the pulp without intermediate washing of the cellulose. A further addition of peroxide is not carried out.

Abstract: A method for cleaning diffusion tiles used in the oxygen distribution system of the biofogical treatment ponds of wastewater treatment facilities is disclosed. The build-up of ferric hydroxide scale, which blocks the pores in such diffusion tiles (55), is removed by (1). purging the oxygen distribution system with a nonoxidizing gas such as nitrogen (10), (2) injecting substantially pure HCI gas (11) through the system which removes the scale, and (3) purging the system again with the nonoxidizing gas before resuming oxygen feed. The use of a nonoxidizing purge gas before and after acid treatment prevents severe corrosion in the oxygen distribution system caused by the simultaneous presence of HCI gas and oxygen.

Abstract: Carbon electrodes are impregnated with pitch during transport in mobile vessels which first travel to a heating station where the electrodes are heated in several stages by gases which are hotter from stage to stage. The vessels next travels to a station where the sealed vessels are connected with a suction pump to evacuate the fluid from their interiors and from the pores of the electrodes therein and where the vessels are substantially filled with pitch which is caused to penetrate into the empty pores. The vessels then travel to a station where the contents of the vessels are pressurized to ensure complete permeation of electrodes with pitch. The vessels subsequently travel an optional station where the electrodes in the vessels are baked to convert the pitch into coke, and to one or more cooling stations where the electrodes are heated by air, water and/or nitrogen. Fumes which develop during heating, evacuation of fluid from the pores, baking and cooling are filtered to avoid contamination of the surrounding area.

Abstract: arge single crystals of berlinite are grown onto seed crystals by maintaining the crystals at a fixed elevated temperature in a pressure vessel containing a nutrient of coarse berlinite crystalline powder, held at a fixed lower temperature, and concentrated phosphoric acid. Because berlinite shows retrograde solubility, the nutrient goes into solution, and berlinite deposits on the higher-temperature growing crystal. The vessel is rocked to promote motion of saturated solution to the crystal and depleted solution to the nutrient. Large single crystals of alpha-gallium orthophosphate may be grown using the same apparatus and a similar process. The resultant crystals may be cut into wafers useful in surface acoustic wave devices.

Abstract: A semiconductor buffer circuit which is energisable by a power supply (Vcc,Vss) comprises an input stage (Q1-Q4) for receiving an input clock signal (φ 0 ) and an inverted input clock signal ( φ   0 ). A bootstrap circuit (Q5-Q7), which includes a transistor (Q6) for receiving the output of the input stage circuit, maintains the gate voltage of that transistor at a high level during a standby period. An output circuit (Q8-Q12), including a transistor (Q11) which is switched on and off by the output of the bootstrap circuit, generates an output clock signal (φ 1 ). The circuit is characterised by a current leak circuit (X) which maintains, during the standby period, the voltage of a point (N2) in the semiconductor circuit which is charged during the standby period to a level corresponding to the voltage (Vcc) of the power source. A delay in the output clock signal, which is caused by a fluctuation in the voltage of the power supply during the standby period, is thereby reduced, so that the circuit can be used for fast accessing of a dynamic memory. The current leak circuit (X) may comprise two field-effect transistors (Q13,Q14) connected in series, or various arrangements of field-effect transistors and/or resistors.
